BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 507,648, dated October31, 1893. Application filed October 6, 1892- Serial No- 447,990- (Nomodel-7 To 00% whom it may concern.-

Be it known that I, GEORGE OARNELL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBrick-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in brickmachines, and more particularly to the striker or pusher which operatesto remove the mold from beneath the plunger after the latter hasperformed its function and started on its return stroke.

The main object in view is to prevent injury to or breakage of thepusher or striker and its operating mechanism in case a stone or otherobstacle in the mold should interfere with its being readily moved bythe pusher or striker. When this occurs means is provided for permittingthe full movement of the pitman without movement of the pusher orstriker. A novel and efficient construction and arrangement of parts isprovided for accomplishing this result.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in Which--- Figure 1 is a face view of myim provedmachine. Fig. 2 is a view at right angles to Fig. 1, with parts brokenaway and portions in section.

Like letters of reference indicate like parts in both of the views.

Referring now to the details of the drawings by letter, A designates theframing of the machine and in which the operating parts are mounted andsupported. It may be of any suitable form of construction, and insuitable boxes or bearings a near the upper portion thereof is journaledshaft B carrying the fast and loose pulleys B and B respectively of anyapproved construction.

as seen in Fig. 1, the said pulleys being omitted from Fig. 2. On thisshaft is a small pinion O which meshes with a large pinion O on theshaft C journaled in suitable bearings or boxes 0 on the framing asshown in Fig. 1, and on this shaft near one end is abevel pinion D whichmeshes with the crown wheel D on the stirrer shaft D which is journaledin suitable bearings and is designed to-operate the stirrer (not shown)in the clay box or chamber'D which is provided with an outlet d for thepassage of the clay to the mold as will be understood from reference toFig. 2 where the end of the clay box is broken away. On the other end ofthis-shaft O is a pinion E which meshes with a larger pinion E on ashaft E journaled in suitable boxes or bearings b on the frame as seenin Fig. l and provided with the cranks b as also shown in said figure.

F is the plunger which may be of any well known construction moving inthe box E" and carried by the rod F which is uided at its upperend in asuitable guide f on the front of the clay box and upon this rod is screwthreaded a nutor collar f between which and a pin or projection f theyoke G is sleeved upon the plunger rod, the said yoke being connected atits ends with the cranks b of the shaft E by the rods or links G asshown whereby the required reciprocatory motion is imparted to theplunger by the revolution of the said shaft by the gears E and Eactuated from the main power shaft by the gears O and O as will bereadily understood from the drawings. The bed H upon which the mold boxis designed to be supported is rendered vertically adjustable to meetthe requirements in any suitable manner, as by the jacks H Rails H arealso provided for the support and guidance or the pusher or striker aswell as for the molds, as seen in both of the views. The molds H maybeof any suitable construction having a bottom as seen in Fig. 2 andsupported upon the rails beneath the box F as shown.

I is a scraper bar arranged over the front rising from this scraper arethe pins 1' which are arranged tohave their upper ends pressed upon bythe arms J which are pivoted as at 7' and provided with adjustableweights j as seen in Fig. 1 and resting upon the upper ends of saidpins. The end J of the portion over the scraper is hinged at one end inany suitable manner so as to be thrown open in case any necessitypresents itself for access to the pins and upon this hinged part aresuitable flanges or cleats 7' which serve to limit the outward movementof the scraper as seen in both of the views.

K is a lever pivoted at 7- to the part J"as at the center as shown in Fi1 and to this lever between its ends is pivoted one end of a link K theother end of which is pivot-ally connected with the scraper so that thelatter may be thrown upward when desired by a simple movement of thesaid lever as will be readily understood from Fig. 1.

The gear wheel E has aninwardly-extending flange e as seen in Fig. 2,which is provided with a curved slot e as is also shown in said figure.

L is a rod or link having one end adjustably held in this slot and itsother end pivotally connected with an arm L which in turn is pivoted atits other end to the arm M held to one end of a rock shaft M journaledin suitable bearings near the base of the machine as shown. The rod L ismade in two or more parts adjustably connected in any suitable manner asfor instance by a turn buckle Z as shown so as to lengthen or shorten itwhen occasion may require. The arm M which extends in an inclineddirection as seen in Fig. 2, has pivotally connected with its upper endas at Z a horizontal rod N which is provided with an adjustable weight nrendered adjustable on the arm in any suitable manner as for instance bya set screw n as seen in Fig. 2. The arm N has near its pivot a lug orextension I in which is affixed a pin 11*, and upon this extension orlug is pivoted as at m a latch m having a hook m as seen in Fig. 2, thelower end of the latch being designed to normally impinge against theupper end of the arm L' as seen in Fig. 2, and the hook engaging the pina as seen in Fig. 2.

On the rock shaft 31' are two or more arms which have connected theretoat their upper ends the curved arms 0 which are attached to thecarriageP provided with wheels 0 and running upon suitable guides ortracks as seen in Fig. 2. This carriage carries the pusher or striker ormold-ejector Q, which is designed to travel in a horizontal plane and toeject the molds after the clay has been compressed therein by thefiller-plunger.

. In operation, the parts are so timed that the molds haviugbeen placedin position the filler-plunger descends and presses the clay therein,and as the gear wheel E continues its revolution the arm M is moved inthe direction of the curved dotted line in Fig.2 and the pusher orstriker moved forward to eject the mold; if no obstruction is met theparts continue on their course without interference, the arm M, arm L,arm N, rod L and latch being held in theposition in which they are shownin Fig. 2, but should there be a stone or hard lump in the mold orfiller box and so situated as to prevent the mold being ejected, thelatch will be disengaged from its pin 01 which will leave the armN freeto drop by reason of its weight and thus the free end of the latch willbe withdrawn from its ongagement from the arm L when the latter with therodL can continue their movements without actuating the pusher orstriker as will be readily understood. The stone or obstacle can beremoved by swinging the part J on its hinge and then the machine canresume its movements.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages.

hat I claim as new is 1. In a brick machine, mold-ejecting mechanismcombined with a weighted arm with a pivoted latch, and a supplementalarm and a pin for engaging said latch constructed to render themold-ejecting mechanism automatically inoperative to prevent injurythereto it an obstruction be met in the mold, substantially asdescribed.

2. In a brick machine, mold-ejecting mechanism combined with an arm witha pivoted latch and a supplemental arm having means for engaging thelatch and constructed to be automatically disconnected it the ejectingmechanism meet with an obstruction in the mold, substantially asspecified.

In a brick machine, the combination with the mold-ejector, and the rockshaft with connections thereto, of the arm on the rock shaft, the armpivoted thereon, the horizontal weighted arm pivoted on thefirstmentioned arm, the latch pivoted on the weighted arm with one endengaging the second arm, and a pin on the weighted arm for engaging theother end of said latch, as and for the purpose specified.

4. In a brick machine, the combination with the mold-ejector and itsactuating mechanism, of a weighted arm carrying a pivoted latch fornormally holding the ejector and its operating devices in position tomove simultaneously but permitting disengagement by the presence ofanobstruction, as set forth.

5. In a brick machine, the combination with the filler-box, of a scraperhaving vertical pins working loosely in vertical openings, the weightedarms independent of and bear iug upon said pins, the hinged part havingvertical guides for the scraper, and the lever pivoted on said hingedpart and connected with the scraper, as set forth.

6. In a brick machine, the combination with the mold-ejector, and itsactuating mech- In testimony whereof I affix my signature in presence oftwo witnesses.
